Nitrogen introduction [ 2020-09-02 ]
The chemical formula is N2, which is usually a colorless and odorless gas, and nitrogen is generally less dense than air. Nitrogen accounts for 78.08% (volume fraction) of the total atmosphere and is the main component of air. Under standard atmospheric pressure, when cooled to -195.8°C, it becomes a colorless liquid, and when cooled to -209.8°C, liquid nitrogen becomes a snow-like solid. Nitrogen is chemically inactive and difficult to react with other substances at room temperature, so it is often used to make preservatives. However, it can undergo chemical changes with certain substances under high temperature and high energy conditions to produce new substances useful to humans.
